摘要翻译:
我们提出了一个新的信用指数衍生产品模型,在自上而下的方法。该模型具有波动性和跳跃的动态损失强度过程,并可包含交易对手风险。它处理CDS、CDO分期、N次违约和指数互换。利用仿射模型的性质,我们导出了指数CDS、CDO分期和N次违约定价的封闭公式。对于指数交换,我们给出了一个精确的定价和一个近似的快速方法。最后给出了对2009年市场数据的校正结果。

英文摘要:
We present a new model for credit index derivatives, in the top-down approach. This model has a dynamic loss intensity process with volatility and jumps and can include counterparty risk. It handles CDS, CDO tranches, Nth-to-default and index swaptions. Using properties of affine models, we derive closed formulas for the pricing of index CDS, CDO tranches and Nth-to-default. For index swaptions, we give an exact pricing and an approximate faster method. We finally show calibration results on 2009 market data.
